SWC plugin for Vite and Rollup
npm install unplugin-swc
> SWC plugin for Vite and Rollup.
``bash`
npm i unplugin-swc @swc/core -D
Vite or Rollup:
`ts
import swc from 'unplugin-swc'
export default {
plugins: [
// Vite plugin
swc.vite(),
// Rollup plugin
swc.rollup(),
],
}
`
Following SWC options are inferred from tsconfig.json:
- jsc.parser.syntax: based on file extensionjsc.parser.jsx
- , parser.tsx: compilerOptions.jsxjsc.parser.decorators
- : compilerOptions.experimentalDecoratorsjsc.transform.react.pragma
- : compilerOptions.jsxFactoryjsc.transform.react.pragmaFrag
- : compilerOptions.jsxFragmentFactoryjsc.transform.react.importSource
- : compilerOptions.jsxImportSourcejsc.transform.legacyDecorator
- : compilerOptions.experimentalDecoratorsjsc.transform.decoratorMetadata
- : compilerOptions.emitDecoratorMetadatajsc.keepClassNames
- : when decorator is enabled, because original class name is required by libs like type-graphql to generate correct graphql type
If you wish to disable this behavior and use .swcrc to control above jsc options, you can use tsconfigFile option:
`ts
// Or swc.rollup
swc.vite({
tsconfigFile: false,
})
// It's also possible to use a custom tsconfig file instead of tsconfig.json
swc.vite({
tsconfigFile: './tsconfig.build.json',
})
`
Use the minify: true option, it only works for Rollup as Vite uses esbuild to minify the code and cannot be changed.
To have advanced control over the minification process, use jsc.minify option in .swcrc.
esbuild will be automatically disabled if you use this plugin.
This plugin accepts all @swc/core options, except for jsc which should be configured in .swcrc instead, and some extra options that are specific to this plugin:
- Type: boolean, stringtsconfig.json
- Default:
Disable the use of tsconfig file or specify a custom one.
- Type: RegExp/\.[jt]sx?$/
- Default:
Files to include in the transpilation process.
- Type: RegExp/node_modules/
- Default:
Files to exclude in the transpilation process.
- Type: object`
Custom jsc options to merge with the default one.
